This rugged and versatile unit is used to power a small load at 12V from a 24V battery, or to power a small 24V load from a 12V battery.
It functions both ways, producing 12V @ 20 Amps from a 24V input or can be connected backwards to produce 24V @ 10 Amps from a 12V input.
When connected as a battery equalizer, it allows large transient 12V loads to be taken off the centre tap of a 24V battery (made of 2 X 12V batteries) without fear of upsetting the voltage balance of the battery and destroying the 24V battery system that would otherwise occur. |
